Why do ".vmx~" files appear as wasted and how can I exclude them from storage policy

There are files with the extension ".vmx~" in the directory with every VM and Turbonomic has flagged them all as wasted. I believe those files are required by VMWare but I'm not sure. Wondering how I would exclude them from storage policy.

A .vmx file with a '~' (tilde) is an EDIT file. When a VMX file is being edited (say you're modifying VM config, adding a disk, etc), this file is created temporarily, until the changes are completed, at which time it should be swapped with the .vmx file you see in the directory. If you have a process that's not completing edits or a sysadmin that's editing .vmx files directly, you'll see this. If there's no reconfiguration in process, these files truly are wasted.

To exclude them from discovery, go to Settings > Policies, and open up your Storage policies. At the bottom of the list, you should see an option for 'exclude', add .*\.vmx~ to the list.
